No biocontrol agent has been reported from Rhizosphaera.
Biochemical importance of the genus, chemical diversity or applications
The chemical diversity of Rhizosphaera is unknown. Further studies are needed.
Diversity of the genus
Rhizosphaera comprises eight species known on several hosts but one plant family namely Pinaceae. Rhizosphaera seems to be host specific. Rhizosphaera is reported from several countries such as Europe (Russia, Austria, France, Germany, Czechoslovakia, Norway, Britain, Ireland, Netherland), North America (United States, Canada), Asia (Japan).
